Pepsin

pepsin

(Science: protein) acid protease from stomach of vertebrates. Cleaves preferentially between two hydrophobic amino acids (e.g. F L, F Y) and will attack most proteins except protamines, keratin and highly glycosylated proteins. A single chain phosphoprotein (327 amino acids, 34.5 kD) released from the enzymatically inactive zymogen, pepsinogen, by autocatalysis at acid pH in the presence of HCl. One of the peptides cleaved off in this process is a pepsin inhibitor and has to be further degraded to allow the pepsin to have full activity. An enzyme produced in the stomach that splits proteins into peptones.A type of [[enzyme secreted by the gastric pits of the [[stomach which breaks [[proteins (polypeptide chains) into smaller polypeptide chains which can then be further broken down into [[amino acids by [[peptidase.

Rennin and New born babies.

... animals, such as the cow, produce it - rennin used to be extracted from the stomach of the calves for commercial use as far as I know. In humans, pepsin performs the same function, i.e. coagulates milk proteins. You sure you got the name right? Humans produce renin that is secreted (as the name ...

Re: Stomach bloating and weight gain

... its shape. and changes in some way or another. The stomach acids create a pH environment which normally denatures a enzyme or protein. The enzyme pepsin is an exception to this rule however as it does survive the pH level of the stomach. This brings me to my second point. The digestive enzymes ...
